| Abstract: | A dual-wavelength fiber laser with a narrow bandwidth,based on a high finesse fiber ring filter has been proposed.Polarization-maintaining fiber Bragg grating(PM-FBG) and a high finesse fiber ring filter are introduced based on the traditional fiber laser.PM-FBG is used as the wavelength selection device to produce dual-wavelength.The fiber ring filter consists of two optical couplers and a section of weak pumped erbium-doped fiber(EDF).Because of the delay of cavity length and the gain generated by the EDF... |
